The bus was stopped at the border between Michigan and Canada and authorities seized both marijuana and drug paraphernalia from it. However, Bieber was not in the bus.

According to Ken Hammond, chief customs and border protection officer, the bus was pulled over at the Ambassador Bridge - which separates Windsor, Canada and Detroit, after a drug-sniffing dog detected the presence of weed on board.

Drugs were seized and the driver was issued a citation.

The driver and passengers were subsequently released.
